To go astray; deviate, as from a moral, religious, or philosophical course.

It's known as tulpa, or thoughtform, a phenomenon where the belief of a group of people causes a being or object to manifest and, sometimes, take on a life of its own. But what happens when these beings break away from the control of their creators and begin to live alongside all of us?

Strays is a myth and folklore RPG based around the existence of these thoughtforms - not only from myth and folklore, including those from Judeo-Christian religions, but also anthropomorphic personifications and historical figures.
